1. In turbine engines that utilize a pressurization and dump valve, the dump portion of the valve A. cuts off fuel flow to the engine fuel manifold and dumps the manifold fuel into the combustor to burn just before the engine shuts down. B. drains the engine manifold lines to prevent fuel boiling and subsequent deposits in the lines as a result of residual engine heat (at engine shutdown). C. dumps extra fuel into the engine in order to provide for quick engine acceleration during rapid throttle advancement.
